Need to repair many IBM G74 Monitor, Model #6547-0AN

I am part of an I.T. shop for a company that has many many many of these IBM G74 monitors. They are gradually starting to all have problems

1. Very dark - Brightness/Contrast controls are not effective and are maxed out

1. Display wider than screen - Width adjustment has very little effect

We have so many, but I'd like to figure out what to look for and how to repair them. I'm really starting to feel stupid and wasteful when we are told to just "junk 'em" and get another. They're fantastic monitors. I am sure the company (or at least the organization that I support) would be somewhat impressed if I could repair them with little trouble and expense.

The other rather embarrassing fact is that I have a EE degree! It was almost all book-smarts if you know what I mean and was not really electronics, per se. I have not been in the electronics nor the engineering world since 1991! I have a FLUKE DMM (at home...don't have the model # with me) and I have soldering tools. I actually have access to an entire workforce of component people (our value add shop), but I'd like to eventually do this myself.

Can anybody help me here?

Thanks, John

PS, I'm in the DFW area (Dallas/Fort Worth, Texas)
